Review comment:
> To me, task.timeout.ms applies mainly to the regular processing case.
For task revocation/corruption it seem ok to ignore the timeout and just reset
it
Ok...I honestly didn't follow KIP-572 too closely but that's what I was
thinking originally and then I got paranoid. But I managed the changes so I
could just revert the last commit if that's how you responded. Sounds like
that's the plan -- please give it one hopefully final pass once I do and we can
finally wash our hands of this
>Or should we only reset the timeout if the cleanup is successful?
The cleanup (you mean `closeAndRevive` right?) shouldn't ever really fail,
but yeah I guess we can just reset it after that returns
